FFX-2 was a mixed bag. It's gameplay was nothing like FFX's, but it was actually pretty fun. The main problem I think people had with it was that the main character, Yuna, acts quite differently than she did in FFX. This is explained through the story, but it is still a bit jarring. Also, the whole Yuna, Rikku, Paine thing is very reminiscent of Charlie's Angels, which makes it a bit hard to take the story very seriously at times. I did like how many of the environments were from FFX, but they were still greatly affected by the events that transpired in FFX. All in all, FFX-2 can be found for pretty cheap now, so if you're even a bit interested, then it's worth checking out. Like other FF's, the side stuff can majorly suck up some time, so be prepared.
